2 days ago I added MA because my PH was high. That brought it down to 7.1, and a TA of 90. I checked today and my PH is already up to 8.0 but my TA dropped to 70.
That doesnt make sense to me. My PH seems to always rise, and thats with NO use of the pool, no aeration except for the one jet my pool has. It rained lightly for about 15 mins last night, but I thought that would lower PH.
Im kind of confused.
